Over 45,000 spectators experienced historic motorsport once again during the second weekend of May. More than 500 different legendary racing cars were on display at the legendary Hockenheimring. From vintage Formula cars to relatively modern Formula 1 vehicles, Touring cars and current sports cars were all present. Well-known marques from the past, such as Lotus, Ford, Ferrari, Fiat, Alfa Romeo, and Porsche, roared their engines. The popular event is affectionately known as the "Jim Clark Revival." This year would have been the 90th birthday of the Scotsman, considered as the greatest Formula One talent of the 1960s. Opel had an impressive exhibition on the roof of the pit complex, and the former Mercedes building once again hosted an exhibition dedicated to Jim Clark.
